Where do the most polite business owners in America live? New research from FreshBooks reveals Oklahoma, Alabama and Ohio have the most polite small business owners in the country. FreshBooks recently analyzed customer data to uncover which small business owners (by state) are the most likely to use please or thank you on their invoices.
People often visited out of the country and talked about Oklahomans being "quite hospitable and kind" but I never know this was quantified.
Interesting. Do you have anecdotal evidence to support some of this list?
